If a wildcard listen on a port is used anywhere in configuration, 
nginx will listen on a wildcard address and won't try to bind to 
individual addresses.  In particular, this allows to configure 
listen directives with addresses not currently present on a host.

Some details can be found at http://nginx.org/r/listen, see "bind" 
parameter description.

No, you don't.  It's enough to add it anywhere in the 
configuration.
